Three-dimensional shaped object manufacturing device, manufacturing method of three-dimensional shaped object, and three-dimensional shaped object

Abstract

A three-dimensional shaped object manufacturing device is adapted to produce a three-dimensional shaped object by laminating layers using a pasty composition containing granular substances. The three-dimensional shaped object manufacturing device includes a stage in which the composition is supplied and the layers are formed, a side surface supporting section arranged on a side surface of the stage, and an adhesion preventing part configured and arranged to prevent adhesion of the composition on a surface of the side surface supporting section. The stage is movable relative to the side surface supporting section in a lamination direction of the layers.
